It is man's intelligence that makes him so often behave more stupidly than the beasts. Man is impelled to invent theories to account for what happens in the world. Unfortunately, he is not quite intelligent enough, in most cases, to find correct explanations. So that when he acts on his theories, he behaves very often like a lunatic. Thus, no animal is clever enough, when there is a drought, to imagine that the rain is being withheld by evil spirits, or as punishment for its transgressions. Therefore you never see animals going through the absurd and often horrible fooleries of magic and religion. No horse, for example would kill one of its foals to make the wind change direction. Dogs do not ritually urinate in the hope of persuading heaven to do the same and send down rain. Asses do not bray a liturgy to cloudless skies. Nor do cats attempt, by abstinence from cat's meat, to wheedle the feline spirits into benevolence. Only man behaves with such gratuitous folly. It is the price he has to pay for being intelligent but not, as yet, intelligent enough.

~Aldous Huxley
